BIOS Request - Lenovo Yoga L13 Gen3 (AMD)

[maeson]

Hi dear Badcaps-Community,

Somehow an auto update, which I triggered before I left my laptop unattended, bricked my BIOS.
I was able to extract the 2MB BIOS and 16MB BIOS which I will attend. (CH341B black with NeoProgrammer 2.2.0.10)

The Device is a Lenovo Yoga L13 Gen3 and I was able to identify the following specifications:

Lenovo Yoga L13 Gen 3 AMD:
Lenovo Modell: Type 21BB
Artikelnr.21BB006GGE
Seriennummer: PW0A6207
AMD Ryzen™ 5 PRO 5675U
Memory 16 GB DDR4-3200MHz
SSD: 512 GB SSD, M.2 2242, PCIe Gen4, TLC, Opal
Display type: 13,3" WUXG

System Board:
Lenovo BDPLANAR R5PRO 5675U,16G,RZ616,YdTWINyAB
Repalcement Unit: 5B21H47118 (System Board)
2MB Chip: XMC XM25QH16CHIG
32MB Chip: Winbond 74M25JWEIQ 2326 6324 M0031

BIOS: Update

Problem:
At first The Escape and F1 LEDs were providing some light but no further reaction. I used the hardware reset button and now the LEDs aren't shining anymore. Nevertheless, tried everything to recover the laptop, support-Keyboard and Power kombinations, nothing worked so far, could any of you be so helpful and assist me with a useful BIOS binary?

Ps.: It is the first time I have to solve such an issue, I hope the provided information are suitable and fit the purpose.

Best regards

The Serial Number is the PW-0A6207.
Does anyone can help? Does anyone has a working BIOS? Is it possible to use similar BIOS? (which i highly doubt).

So I've been trying to remove the supervisor password by following the forum for the automated script to remove it but I am having extreme difficulty finding my specific bios chip. So far I can only find the bios2 chip which is GD25Q16ESIG, where it says bios1 on part of the mother board it doesn't look like there is any chip that correlates to it at all.

Please help me .
SN : PW-05HHNZ Type : 21BC-S04W00
Thinkpad L13 Yoga Gen 3
It has the AMD processor

Or is the second image the chip I've been looking for ? I looked up the info on it GD25LR256EYIG is I believe the 32mb ? And the other one is the 16 ? Am I right ? And if so, how do I go about getting the bios dump, modifying it, flashing it and writing it, turning the computer on, follow instructions from other thread, press space twice, put no password, ect ect, then shut off, and reflashing original bios, is that how I do it ?

Password is on NPCX997 chip from 2nd picture, you need a special programmer for it, such as SVOD4
